Delta had been contracted during the 2014 remediation at the well site to apply their bioremediation process to excavated and stockpiled soil contaminated with Fraction 2 petroleum hydrocarbons (F2 PHC). Soil sample results from a 2014 Phase II ESA showed F2 PHC concentrations ranging from 170 mg/kg to 1210 mg/kg, with an average of 586 mg/kg in the four samples from the disposal area. Delta was on the site for around 10 hours using their hopper and amendment sprayer machine to treat the approximately 600 cubic meters of fine–grained contaminated soil. The treated soil was conveyed back into the excavation so the bioremediation process could continue.
The client retained Gulo Environmental for sampling of the amended soil piles in May of 2015. Results from the analysis of the samples, taken approximately nine months after the bioremediation process, showed non-detection for F2 PHC, resulting in successful closure of the site.

Sitelab's UVF-3100D is used to test soil to help investigate and clean up sites contaminated by above ground or underground storage tanks (USTs). Soils can be analyzed for extended diesel range organics (EDRO) or extractable petroleum hydrocarbons (EPH). Results correlate well to confirmatory lab methods.

The contamination of soils as a result of prior chemical production can often be unpredictable and diverse. The majority of such pollutants will require an ex-situ treatment method. Many of our VacuDry units can be used for direct-feeding contaminated soils. To reduce the input amount for thermal treatment, the VacuDry units can also be used in combination with soil-washing plants: In this case, customers only feed the high polluted fractions and screened fines (e.g. below 10 mm), as well as the filter-cake from the soil washing process. However, we are able to handle soil contaminated with mercury, hydrocarbons, PAH, PCB, dioxins, furans, organic-lead compounds and many more. VacuDry plants for on-site ex-situ remediation projects are delivered in a modular design.

For over twenty years, BioSolve Pinkwater has been used for Surfactant Enhanced Remediation (SER) to mobilize and solubilize residual NAPL[i], facilitating its recovery and disposal. Depending on soil and plume characteristics, Pinkwater solution can reach contaminated zones through deep injection wells or be gravity fed from surface level injection galleries. After desorbing residual NAPL from soil surfaces on contact, Pinkwater then solubilizes the hydrocarbons in an aqueous emulsion, enabling extraction at down gradient recovery wells or trenches.

Toxic hydrocarbons in groundwater can be found dissolved in water diffused over the area. At higher concentrations they can be present as DNAPLs (dense non-aqueous-phase liquids) or LNAPLS (light non-aqueous-phase liquids) creating an enduring source of toxic contaminant supply to the water phase.

The Series 8900 Naphthalene Analyzer provides direct measurement of Naphthalene in ambient air. This instrument is utilized in industrial plants to monitor workplace exposure limits and at remediation and Superfund sites. The Series 8900 Naphthalene Analyzer employs a photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column. At sample injection a fixed volume of sample is carried to the pre-cut column. Backflush is timed so that only the Naphthalene and other similar components are eluted to the analytical column. Contaminants on the pre-cut column are backflushed to vent. Naphthalene is separated from potentially interfering components on the analytical column and elute to the detector for analysis.

Today bioremediation is successfully used as soil– and groundwater remediation technology. Many bioremediation systems, both in-situ as ex-situ techniques, usually result in considerable cost savings. Since the beginning of the 1980’s both in-situ and ex-situ bioremediation projects have been successfully completed worldwide through the use of preselected and adapted bacteria. QM Environmental Services supplies a range of microbial, bioactivator and nutrient products and gas delivery systems for the use in both aerobic and anaerobic bioremediation programs. Most common contaminants ranging from aliphatic hydrocarbons such as petroleum, lubrication oils, aromatic compounds like benzene and toluene to chlorinated solvents can be treated with these products.
